A method for introducing a reflective, refractive, and/or diffractive variable and/or non-variable image to a substrate by use of thermal transfer printing includes simultaneously transferring a defined portion of each of a protective coating layer, an image layer, and an adhesive layer from a carrier film of a transfer ribbon to the substrate by applying heat to the transfer ribbon. The defined portions of the image layer and the protective coating layer are adhered to the substrate using the adhesive layer. Subsequent to transferring the protective coating layer, the image layer, and the adhesive layer, durability is provided to the image layer by cross-linking the protective coating layer that is over the image layer by exposing the protective coating layer to a radiation source after the defined portions of the protective coating layer, the image layer, and the adhesive layer are transferred from the carrier film.

Thermal transfer ribbon assembly comprising a metal layer and a protective coating layer

A method for introducing a reflective and/or diffractive metallic variable and/or non-variable image to a substrate by use of thermal transfer printing includes simultaneously transferring a defined portion of each of a protective coating layer, a metal layer, and an adhesive layer from a carrier film of a transfer ribbon to the substrate by applying heat to the transfer ribbon. The defined portions of the metal layer and the protective coating layer are adhered to the substrate using the adhesive layer. Subsequent to transferring the protective coating layer, the metal layer, and the adhesive layer, durability is provided to the metal layer by cross-linking the protective coating layer that is over the metal layer by exposing the protective coating layer to a radiation source after the defined portions of the protective coating layer, the metal layer, and the adhesive layer are transferred from the carrier film.

A card assembly includes an insulating planar body and a magnetic stripe assembly coupled with the planar body. The magnetic stripe assembly includes a magnetic layer configured to magnetically store information and a metal layer that provides at least one of a security feature, a decorative feature, or other functional feature. The metal layer has a small thickness such that the metal layer prevents conduction of electrostatic discharge (ESD) through the magnetic stripe assembly.

Non-conductive magnetic stripe assembly

A laminated core stock sheet for use in a composite laminate assembly that is separated into individual cards is provided. The sheet includes a core substrate layer and an intermediate filmic layer coupled to the core substrate layer. The intermediate filmic layer includes a conductive material that provides a security, decorative, or functional feature of the cards. The core substrate layer and the intermediate filmic layer are coupled with another laminated core stock sheet to form the composite laminate assembly. The conductive material has a small thickness within the intermediate filmic layer such that the intermediate filmic layer prevents conduction of electrostatic discharge (ESD) through the intermediate filmic layer and outside of the individual cards.

Composite laminate assembly used to form plural individual cards and method of manufacturing the same

A laminate sheet includes a base film formed from a recyclable, biodegradable, degradable, and/or compostable material, a metal or reflective film layer disposed over the base film, and heat resistant layer disposed over the base film.

Decorative and/or secure element for homogeneous card construction

A laminated core stock sheet for use in a composite laminate assembly configured for being separated into plural individual cards is provided. The laminated core stock sheet includes a core substrate layer and an intermediate filmic layer coupled to the core substrate layer. The intermediate filmic layer includes plural conductive bodies spaced apart from each other that provide at least one of a security feature, a decorative feature, or other functional feature of the individual cards. The core substrate layer and the intermediate filmic layer are configured to be coupled with another laminated core stock sheet that may or may not include the intermediate filmic layer to form the composite laminate assembly configured for being separated into the individual cards.

A laminate assembly and method for manufacturing a laminate assembly for a card assembly is provided. The assembly includes a top coat layer, a carrier layer connected with the top coat layer, and a colored core coupled by an adhesive layer. One or more of the adhesive layer or the top coat layer includes a colorant of a second color that is different from the first color of the colored core such that the first color of the colored core less not visible through the printed surface of the top coat layer.

Card assembly and method of manufacturing the same

A method for the manufacture of a composite laminate assembly that includes decorative, functional, security, reflective, diffractive, holographic elements for liquid transfer onto the surface of a variety of base materials or work piece having a flat or complex three dimensional shape.
